Near the knifeI put apair offeed 11 rolls D which withfthe'` trough or boX may 1 be of anywofthe usualforms which it is thought not necessary todescribe minutely;the wholefI arrange1 with a l frame of con- 1venient `form`` to support`the stationary knife Gand theflangeshaft with boXes `ad1 justable as `by1the 1screws Gr, Gr,y and connect the flangeshaft andfeed rolls by thegear E and F, the relative sizeof whichI vary f1 according to length"desired .to be "cut and onglthe end-ofiiangeshaftnput a or bal- 1 ancewheel, the heads BBbeing set close to the knife, asthey `can well turnand motion 'I given to the machine `so "as to turn the flanges A, A,Nover` toward the knife, the
